Embodiment Construction
[0027] Such as figure 1 As shown, the base plate 22 is a rectangular planar body, and its size can be made: 480mm×300mm. A head ring 23 is arranged in the middle of the board surface of the base plate 22 . Head ring 23 is a kind of silicone cushion, can be divided into adult type and children's type. A head fixing frame is arranged on the base plate 22 near the side of the headband. The head fixing frame includes a column 21, a telescopic connecting rod 20 and a nail clip 19. Cranial nail clip 19 also can be divided into adult type and children's type. The upright post 21 is fixed upright on the base plate 22 , the telescopic connecting rod 20 is pivotally connected to the upper end of the upright post, and the skull nail clip 19 is fixed on the end of the telescopic connecting rod 20 . There are one head fixing frame on the left and one on the right, which are arranged symmetrically to fix the patient's head. Both the head ring 23 and the head holder can be made by using...

The invention relates to a craniocerebral operation directional navigation system and a use method thereof. The directional navigation system comprises a base plate, a head ring, a head fixing frame, a supporting rod, an inclined supporting rod, a base line ruler, double sliding rails, a sliding positioning ruler and the like. The base line ruler is horizontally arranged and is marked with a dimension line representing the length, one end of the base line ruler is provided with an end position laser light source, and a zero position laser light source is arranged on a zero position point of the base line ruler; the sliding positioning ruler comprises a transverse ruler and a vertical ruler, the transverse ruler is supported on the horizontal position through double sliding rails, the vertical ruler is vertically arranged below the transverse ruler through a third sliding sleeve, an axial position laser light source is arranged on the third sliding sleeve, a vector position laser light source is connected to the transverse ruler through a first sliding sleeve, and a crown position laser light source is connected to the vertical ruler through a second sliding sleeve. The directional navigation system for the craniocerebral operation is not limited by an operation site and a body position, the operation field exposure is good, and the directional navigation system for the craniocerebral operation is high in cost performance, easy to operate and high in precision.
Description
technical field [0001] The invention relates to an auxiliary device for brain surgery, in particular to a directional navigation system for brain surgery and its application method. Background technique [0002] Due to the complex structure of brain tissue and few functionally dumb areas, craniocerebral surgery needs to be performed under the premise of as little traction as possible and less damage to brain tissue. The operative field is narrow and the field of view is poor. Therefore, it is easy to get lost during the operation, especially when performing deep brain surgery, causing unnecessary iatrogenic damage. At present, in the hematoma puncture and drainage operations carried out in various places, some primary hospitals are limited by high-priced medical equipment. Most operators use blind puncture surgery or simple positioning rulers for positioning surgery based on experience. There is a risk of deviation in puncture direction and depth, and iatrogenic injuries occ...
